Test includes:
Qualitative detection of IgM antibodies to Rubella virus.
Methodology:
Chemiluminescence
Synonyms:
RUBELLA IGM ANTIBODY, RUBELLA ANTIBODY, RUBM
Clinical significance:
Rubella (German measles) is a usually benign childhood viral infection for which a vaccine is available. IgM antibody is detectable 11-25 days after the onset of exanthem, 12-25 days after vaccination, and in most infants with congenital rubella between 2 weeks and 3 months after birth. A positive rubella IgM antibody in conjunction with clinical findings may indicate an active or recent infection with rubella virus.
